Described herein are methods, systems, and apparatus for performing device-to-device (D2D) discovery in an unlicensed band. In one example, a method for wireless communication is described that includes identifying a resource pool for D2D discovery in an unlicensed radio frequency spectrum band and selecting a set of resource blocks in the identified resource pool. The method may also include performing a channel occupancy check for the channel in the selected set of resource blocks. The method further includes transmitting a D2D discovery message based at least in part on the channel occupancy check, the D2D discovery message transmitted over the selected set of resource blocks in the unlicensed radio frequency spectrum band. |
